A shock of color on the Moon! The Lassell Massif (a so-called "red spot") in Mare Nubium appears orange in the center of this WAC color composite image. The image was derived by assigning red to 689 nm, green to 415 nm, and blue to 321 nm images. The image was enlarged by a factor of two for viewing here (the original data was sampled to 400 m per pixel); north is up. Image is 190 km across. [NASA/GSFC/Arizona State University].
